Feedback in the cores of clusters A3581, 2A 0335+096, and sersic 159-03

Farage, Catherine; McGregor, Peter; Dopita, Michael


The cores of massive galaxy clusters, where hot gas is cooling rapidly, appear to undergo cycles of self-regulating energy feedback, in which active galactic nucleus (AGN) outbursts in the central galaxies episodically provide sufficient heating to offset much of the gas cooling. We use deep integral-field spectroscopy to study the optical line emission from the extended nebulae of three nearby brightest cluster galaxies and investigate how they are related to the processes of heating and...[Show more]
